Optimized Extraction of Amikacin from Murine Whole Blood

Completely automated extraction of DNA from whole blood.

Labdisk Integrated Dna Extraction from Whole Blood Using Magnetic Particles

Integration of sample preparation is a key issue in the development of point of care diagnostic devices. We address the integration of a magnetic-particle based DNA extraction from 200 μl of whole blood into a centrifugal-microfluidic LabDisk. Quality of LabDisk extracted DNA was compared to DNA extracted by commercial spin columns as golden standard with four independent extractions from one b...

Direct PCR from whole blood, without DNA extraction.

Typically DNA used in PCR assays is usually extracted according to die phenol-chloroform method (1) or by an alternative 'saltingout' rapid purification (2). Moreover partially purified DNA obtained with rapid procedures have been reported to be suitable for PCR amplification (3). We describe here a more simple and efficient method to amplify DNA directly from whole blood samples without any pu...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

On-chip Extraction of Intracellular Molecules in White Blood Cells from Whole Blood

The extraction of virological markers in white blood cells (WBCs) from whole blood--without reagents, electricity, or instruments--is the most important first step for diagnostic testing of infectious diseases in resource-limited settings. Here we develop an integrated microfluidic chip that continuously separates WBCs from whole blood and mechanically ruptures them to extract intracellular pro...
